Buat yang belum tau, sistem drainase bawah tanah terbesar dunia ada di bawah kota Tokyo.
Auto aktif ketika hujan deras. Mereka bisa pompa 200 ton air per detik dengan 78 pompa di kedalaman 50 meter mengalir di terowongan sepanjang 6.3 km di bawah tanah Tokyo.
Dibangun pada tahun 1992 - 2006 dengan memakan biaya sekitar $2.6 Milliar atau sekitar 46 Trilliun Rupiah.
Efeknya? Kerusakan banjir turun drastis dan World Bank Group perkirakan akan menghilangkan kerugian banjir sekitar $52 milliar per tahun di tahun 2050.
Ini bukti serius lawan banjir itu investasi jangka panjang.
Kapan Indonesia bisa punya sistem banjir seperti ini?
Elon Musk explains his 5-step algorithm for solving any problem:
"The most common mistake of smart engineers is to optimize a thing that should not exist."
"I have this very basic first principles algorithm that I run as a mantra."
Elon breaks it down:
Step 1: Question the requirements.
"Make the requirements less dumb. The requirements are always dumb to some degree, no matter how smart the person who gave you those requirements. You have to start there, because otherwise you could get the perfect answer to the wrong question."
Step 2: Try to delete it.
"Try to delete the part or the process step entirely. If you're not forced to put back at least 10% of what you delete, you're not deleting enough. Most people feel like they've succeeded if they haven't been forced to put things back in. But actually they haven't, they've been overly conservative and left things in that shouldn't be there."
Step 3: Optimize or simplify.
"The most common mistake of smart engineers is to optimize a thing that should not exist. So you don't optimize until after you've tried to delete."
Step 4: Speed it up.
"Any given thing can be done faster than you think. But you shouldn't speed things up until you've tried to delete it and optimize it otherwise, you're speeding up something that shouldn't exist."
Step 5: Automate.
"And then the fifth thing is to automate it."
Elon explains why the order matters:
"I've gone backwards so many times where I've automated something, sped it up, simplified it, and then deleted it. I got tired of doing that. So that's why I have this mantra."
Hewan Langka Khas Papua
Kangguru Pohon Wondiwoi
ia sudah pernah di nyatakan punah sejak puluhan tahun yang lalu
Hewan langka ini kembali ditemukan di Papua Barat dan juga kembali terancam punah akibat pembabatan Hutan yang terus berlangsung di Papua
Dia tetap datang paling awal ke rumah Allah.

Dia sempurnakan dengan penuh tenang.(Berwuduk✅)
Dia tidak tahu itu kali terakhir dia membuka cahaya rumah Allah, yang menerangi orang lain.(Berkhidmat di rumah Allah✅)
Dia tidak tahu itu bacaan Al-Quran terakhirnya
Elon Musk: "If you punish people too much for failure, then they will respond accordingly, and the innovation you will get will be very incrementalist
Nobody's gonna try anything bold for fear of getting fired or being punished in some way. So risk-reward must be balanced and favor taking bold moves, otherwise it will not happen"
